AN00235 - Butterfly wings - a fragile biological nanostructure

Butterfly wings derive their colour both from the structure of the scale cells on their surface and from pigment grains.
Lithography by Local Oxidation of Titanium 10x10µm image, z-range: 1.60µm

The image shows a AFM measurement of these optically invisible, fragile structure of a Butterfly wing.

The measurement was done in "Dynamic Force" operating mode.
Lithography by Local Oxidation of Titanium 18.8x18.8µm image, z-range: 5.6µm
This image shows a Wing of a Peacock Butterfly.
It was measured with a Nanosurf easyScan DFM by Michael Drexel & Walter Freyn. Sample preparation Dr. Eckhard Hartmann (Augsburg University, Biology). Advanced Lab Course 20, Augsburg University, EKM, Experimentalphysik 6.
